Funded by the Amgen Foundation, the Teachers' Domain Biotechnology website provides resources on this broad field for educators to use in their classrooms. The materials are divided into four primary areas, including "Applications", "Careers", and "Tools and Techniques". In the "Applications" area, visitors will find over fifteen activities that include "Animal Cloning 101" and "DNA Extraction". Each resource contains an interactive component, and visitors are free to use them as they see fit. In the "Careers" area, visitors can listen to scientists like Andres Berrio talk about his work in biotechnology. The "Tools and Techniques" area contains some rather useful links on how to prepare agarose gel for use in gel electrophoresis and an interactive activity about gene cloning. The site is rounded out by the inclusion of a lesson plan that will help students learn how biotechnology can be used to detect and treat disease.
